例句：His remarks were ____ annoy everybody at the meeting.

A.so as to B.such as to C.such to D.as much as to

D。so 和 such 都有“如此，这么的”的意思。so搭配形容词，such搭配名词。句中既无被修饰的名词也无被修饰的形容词。重点应该在动词“annoy”上，因为它前面可以加个副词词组。也就是as much as to.译文：他的发言让所有与会人员愤怒的无以复加。（as much as to annoy——要多让人生气就有多让人生气）C是个干扰项，也就是本身语法错误。A和B都需要有因果关系的语境才可以使用，显然根据译文是不能用滴。
